To integrate MyGiftList with a site that uses the PinnacleCart.com shopping cart software, first create a MyGiftList Merchant Affiliate Account. Then login to your PinnacleCart control panel and find and click on the link to Activate Cart Designer. In the Cart Designer, go to a product page that displays a single product and right click on the red box around the Add to Cart button. Select "Edit Source Code" in the popup box. The following popup box will contain Source Code. Follow the directions below to cut and paste the "Add to MyGiftList" HTML code below into the Source Code. After this, you will want to add a new page using the "Add a New Page" link to your menu called Registry and add the "Login Code" from your MyGiftList Merchant Affiliate account to this page. This code was tested with Pinnacle Cart version 3.7.11.
